Who knew an algae could be so beneficial?
Spirulina is a blue-green algae which is commercially produced and widely marketed as a "superfood" and immune booster. It is also a rich source of natural, plant-based iron, calcium, vitamin A and vitamin C, and an excellent source of plant protein, with up to 70% of its dry weight being protein. The alpha-linolenic acid profile in spirulina is the highest in the plant kingdom, coming in third overall behind milk and evening primrose oil.
A study published in the Spring 2005 isssue of theJournal of Medicinal Food indicated that ingested spirulina made a significant improvement in human patients with nasal allergies, also known as allergic rhinitis.
